A stacked generalisation methodology for estimating the uniaxial compressive strength of rocksAbstract Uniaxial compressive strength (UCS) has become a highly essential strength parameter in the mining, civil and geomechanical industries. Estimating the exact value of the strength of rock has become a matter of great concern in real life. Despite this, there have been many works to indirectly/directly estimate the UCS of rocks. This study introduces a novel ... ...

Sustainable construction and quality of improved columns with three types of water-cement ratios on deep mixing method in Saga Lowland, Kyushu, Japan
- 2024
In this study, we investigated the application of the deep mixing method (DMM) to cohesive soil in the Saga Lowland of Kyushu, Japan. The study focused on examining three types of water-cement ratio (W/C) conditions, with a constant addition of cement-based binder (C). Due to the soft clay nature of the Saga Lowland, frequent ground settlement and deformation occur, necessitating measures to preve......
The next frontier: data-driven urban underground space planning orienting multiple development concepts
Tập 1 - Trang 1-21 - 2023
In recent years, the comprehensive and extensive development of urban underground space (UUS) has gained substantial popularity with the efficient guidance of UUS planning. This study discussed the research trends and paradigm shift in UUS planning over the past few decades. Bibliometric and comparative studies were conducted to identify the contributions of the research in this field. The analysi......
Performance of eco-friendly concrete: a safe direction to sustainable cities development
Tập 1 - Trang 1-9 - 2023
Constructing sustainable cities for the future usually encounters some challenges such as reducing the environmental footprint through using eco-friendly materials. Coarse recycled aggregate retrieved from demolished concrete structures is considered one of the eco-friendly building materials. This study aims to investigate the impact of strengthened recycled aggregate with pozzolan slurry on the ......
Quantitative characterization method of 3D roughness of rock mass structural surface considering size effect
Tập 1 - Trang 1-12 - 2023
The surface morphology of the structural surface of the rock mass plays a crucial role in determining its macroscopic physical and mechanical properties, including shear strength and seepage characteristics. The morphological characteristics of the rock mass structure exhibit significant anisotropy and size effects. The distribution characteristics of the two key indicators that affect the morphol......
Machine learning approach for predicting compressive strength in foam concrete under varying mix designs and curing periods
Tập 1 - Trang 1-17 - 2023
Efforts to reduce the weight of buildings and structures, counteract the seismic threat to human life, and cut down on construction expenses are widespread. A strategy employed to address these challenges involves the adoption of foam concrete. Unlike traditional concrete, foam concrete maintains the standard concrete composition but excludes coarse aggregates, substituting them with a foam agent.......
Prevention/mitigation of natural disasters in urban areas
Tập 1 Số 1 - Trang 1-16 - 2023
Preventing/mitigating natural disasters in urban areas can indirectly be part of the 17 sustainable economic and social development intentions according to the United Nations in 2015. Four types of natural disasters—flooding, heavy rain-induced slope failures/landslides; earthquakes causing structure failure/collapse, and land subsidence—are briefly considered in this article. With the increased f......
Multi-tier scheduling algorithm of dispatching systems for urban water logging
- 2024
Due to global warming, considerable amounts of storm rain have occurred, causing urban water logging and flooding. The efficient scheduling of drainage systems among pumping stations is crucial to mitigating flash flooding in urban areas. This study introduces a Multi-Level Dynamic Priority and Importance Scheduling (MDPIS) algorithm as a proactive solution for addressing urban flooding through th......
